Fedora 28: 2018-1c1a318a0b Critical: Git Code Execution Risk

Git is a fast, scalable, distributed revision control system with an

unusually rich command set that provides both high-level operations

and full access to internals.

The git rpm installs common set of tools which are usually using with

small amount of dependencies. To install all git packages, including

tools for integrating with other SCMs, install the git-all meta-package.

Upstream security update resolving an issue with `git clone --recurse-submodules`. From the [upstream release announcement](): > These releases

fix a security flaw (CVE-2018-17456), which allowed an > attacker to execute

arbitrary code by crafting a malicious .gitmodules > file in a project cloned

with --recurse-submodules. > > When running "git clone --recurse-submodules",

Git parses the supplied > .gitmodules file for a URL field and blindly passes it

as an argument > to a "git clone" subprocess. If the URL field is set to a

string that > begins with a dash, this "git clone" subprocess interprets the URL

as > an option. This can lead to executing an arbitrary script shipped in > the

superproject as the user who ran "git clone". > > In addition to fixing the

security issue for the user running "clone", > the 2.17.2, 2.18.1 and 2.19.1

releases have an "fsck" check which can > be used to detect such malicious

repository content when fetching or > accepting a push. See

"transfer.fsckObjects" in git-config(1). > > Credit for finding and fixing this

vulnerability goes to joernchen > and Jeff King, respectively.
